eaiuon CHARLES Jan-minim, or nos ANGELES, eanmomvm, ASSIGNOB T BUBNHAM BASKET comm, a conrona'rion or CALIFORNIA.

Box-mire Original application filed August 22,

To all whom it may concern:

Be it known that I, CHABnus BURNHAMQ a citizen of the United States, and a resident of Los Angeles, county of Los Angeles,

and State of California, have invented certain new and useful Improvements in Box- Making Machines, of which the following is a full, clear, and exact description.

This invention relates more particularly to mechanism for folding and bending a metal'strip forming a binding for fruit and berry boxes and the like, and is a division of my pending filed August 22, 1911, now Patent No. 1,119,340, dated December 1, 1914.

One of the principal objects of the invention is to provide simple and eflicient automatic mechanism by which a long metallic strip may be folded lengthwise thereof substantially V-shaped or U-shaped and the folded strip cut the proper length and bent transversely to conform to the shape of the boxes to which the metal binding is applied and to clench the metal binding to the boxes or other object to hold the parts together.

Another-object of the invention is to pro .vide simple and eflicient mechanism by l which a metallic strip may be folded lengthwise and bent transversely-and the ends of the strip caused to overlap so that the said strip maybe bound entirely around a box or object and the ends thereof made to lie substantially flush when the strip is applied to said object.

Other objects of the invention are to pro:

vide simple and eflicient means for bending binding metal around a substantially rectangular anvil or former and to hold the same in position to receive the open end ofga box or objectand so to bend the binding "that the latter is substantially closedat the corners thereof and open between the corners for the reception of the parts of an object; to provide box forming means, a part of which forms a support for the former about which the binding metal is bent; and to provide means'whereby the binding metal may be applied to a box body or other object.

A further object of the invention is to provide simple and eflicient mechanism including a plurality of bodily movable and pivotally held bending jaws which are application, Sr. No. 645,323,

1911, Serial no. 645,323. Divided and. this application filed November 29, 1912. Serial H0. 734,155.

adapted to hold and bend binding an about a former.

With these and other objects in view, the invention will-be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this specification, and will then be pointed out in the claims at the end of the description.

Fig. 67 shows 7 it will be understo'odthat many of the fea tures may be used in. connection wlth other forms of machines-and -.that-some of the parts may be dispensed with or other features substituted therefor without departing from the spirit of the invention.

In the general operation of a box-making machine to whichthis larly applicable, a metallic strip is fed from a reel or otherwise suitably supported convenient to the machine,- and this strip by suitable mechanism is fed to what term forming mechanism, that is the metal 1s bent or formed lengthwise thereof so as to be substantially V-shapedoi-"U-shapedin order to fit over the edge of the'box form. This strip is fed inward and tilted and after being tilted so that it will assume a proper position relative to the edges of the box and the anvil or former about which it is bent according to the shape of the box, the strip is then cut off the proper then fed forward on one side of a substantially rectangular anvil having a shape corresponding to the shape of the open end of the box and until the said strip meets the anvil, when the jaws into which the strip has been previously fed by engagement with the former or anvil will bend both ends of the strip on opposite sides thereof making the same substantially U-shaped. A second pair of jaws engages the free ends of the binding strip and forces the same on the remaining side of the anvil and causes one end of the strip to overlap the other. The shooks of which the'box body is made are placed in two magazines located adjacent to one end'of the machine, and these shooks are automatically fed upward in position to be removed therefrom. A reciprocatory and rotary pneumatic device is provided for this purpose and this device is automatically controlled so that the shooks will be picked up first from one magazine and then from the other so that the shooks as thus picked up will lie crosswise and at substantially right angles to each other. device discharges the crossed shooks into a rotary carrier or turret. A movement is given to the carrier and this places the crossed shooks in the path of box-forming mechanism, and atthe proper time this invention is particuv length. The strip is if the tin The pneumatic mechanism operates to form the shooks into box form and carries the box from above the carrier and forces the upper edgethereof into the binding strip. The binding on to.the shooks thus strip is then pinched holding the box shooks permanently together in box form. Mechanism is provided for stripping'the box and causing the completed box to be deposited into the carrier, and the carrier as it feeds new shooks crosswise to the die mechanism conveys the completedbox into position to be discharged. The completed box is forced out of the carrier into a chute and properly stacked and may be removed in any desired way. The binding metal is usually of tin and is in the form of a narrow strip, as 10, Figs. 1 and 7, and said metal strip may be supported as a roll or reel. or otherwise convenient to the machine and passes to a suitable feed mechanism 11. This feed mechanism, Figs. 1, 2, 5,

6 and 7, is shown as having two feed rolls 12 and 13. shaft 14: and the feed roll 13 to a shaft 15 both of which extend transversely of the machine frame 15 at the upper portion thereof and at one end of the machine. On the shaft 14 is a gear 16 which is in mesh with a gear 17 held to the shaft 15 by which the two feed rolls 12 and 13 may be rotated The feed roll 12 is held to a in unison. The shaft 14 is mounted upon an J arm 18 which is pivoted at 19 to the machine frame 15, and held to the upper end of this arm is one end of a spring 20, one end of which, as 21, is secured to the machine frame 15 and the. other end has a.

thumb nut 22 held thereto by which the tension of the spring 20 may be varied, the said spring serving to hold the feed roll 12 in yielding engagement with the feed roll 13 to compensate for the various thicknesses of binding strip which at most would not likely be very great.

A bevel friction wheel 23 is secured to the shaft or stud 15, and adapted to engage the beveled surface thereof is a second bevel friction wheel or gear 24. The friction surface of these wheels may be of any suitable material. The wheel 24 is clamped and rigidly held to a thimble or bushing 25 between the washer 26 and flange 27 of the bushing 25 by means of a nut 28. The thimble 25 is held to rotate with the shaft-29 and is keyed thereto so as to be adjustable len hwise of said shaft, and said thimble 25 is rotatable in a sleeve 30. sleeve is normally held against rotation in a. split boss of a bracket or frame member 31. The sleeve 30 threaded portion 33 to engage a threaded opening in the frame member 31, and said sleeve'is held between the flange 27 and a collar 3 secured to the end of the thimble 25. By'manuallv rotating the knurled part 32 and sleeve 30 the friction gear 24 may has a knurled part32 and a 129 This
